ABSTRACT:
A multi-electrode welding apparatus is provided which includes a torch body and a least two electrodes, preferably of the non-consumable type, which are adjustably mounted in the torch body so as to be vertically positionable with respect to a workpiece and a nozzle mounted in the torch body. Interchangeable nozzles are provided for the electrodes, each nozzle being removably and interchangeably mounted in the torch body and adapted to be employed in conjunction with either of the electrodes so that one of the nozzles in conjunction with one electrode provides an open arc between such electrode and the workpiece, and another of the nozzles employed in conjunction with the other electrode provides a constricted arc between such electrode and the workpiece.
